An early king of Daventry established the moat monsters in the castle's moat as additional line of defense.[3]

Edward's father: Not much is mentioned about him except that when he died he left the magic Shield to his son. It is also known that the trees around the castle were just as tall while he was ruling the kingdom.Thus it can be surmised he used the same castle, or at least the past one in the same location. It is said his son may have built the current castle (though perhaps that means renovated).
